SPECIFICATION forming part of Letters Patent No. 576,270, dated February 2, 1897. Application filed April 2,1896. Serial No. 585,853. (No model.)

To all whom, t may concern: having a rearward slant on their front edges Beit known that I, EDWARD HUBER, a eitiforming the inclined faces a and an abrupt "zen of the United States, residing at Marion, `fall in the rear forming the faces b. Upon in the county of Marion and State of Ohio, the lower edges of these hars similar teeth are 5 have invented certain new and useful Imformed, comprising similarly-inclined and provements in Threshing-Machines, of which vertical faces c and d, respectively, as plainly the following is a specification, reference beshown in Figs. 3 and 4.

This defect is 8o hereinafter described, and shown in the acovercome in the present device by the em- 30 companying drawings, in which ployment of downwardly-extending slats Figure l is a perspective view of a thresher which form a series of stops that arrest the embodying my invention, one side of which strawnpon the oscillation of the shaker from is broken away to show the interior thereof. being thrown backward between the slats Fig. 2 is an enlarged detached plan view of the upon the screens, and by arranging two or 3 5 separator.

It is also a prefthethreshing-cylinder,itsconcave,the beatererable construction to form the shakers in 45 blades, and the usual screens and fans. three sections arranged as shown in Fig. l,

Rearwardly of the cylinder is located the and to the sides of which are secured bars G, straw-shaker, suspended and adapted to be by means of which motion may be imparted actuated 4in any suitable manner in the tothe separator. Although this is a preferleo thresher and arranged and constructed in the able type for use I do not care to limit myself 5o following manner: to the same, as various other arrangements of A and B are side bars or shakers provided the separator maybe made without departn g on their upper edges with offsets or teeth C, from the spirit of my invention.

In operation the straw, after passing through the threshing-cylinder, is received upon the separator and discharged therefrom at the rear of the machine. The downwardly-proj ectin g slats E come in contact with the straw, preventing the same from -falling through the separator upon the screens below, and by the motion of the racks discharge the same from the machine.

Having thus described my invention, what l claim, and desire to secure by Letters Patent, is-

l. In athreshirig-machine, the combination with two or more shaker-bars forming the sides of the separator-frame having a plurality of offsets or teeth upon their lower edges, and two series of slats or bars arranged upon the offsets, one of which series is adapted to project below the other to arrest the straw.

2. In a threshin g-machine, the combination of two or more sh aker-bars forming the sides of the separator-frame, having a plurality of offsets or teeth upon their lower edges, and two series of slats or bars arranged in pairs upon the inclined faces of the offsets or teeth, one of which series is adapted to extend below the other for the purposes described.

A grainseparating device for threshingmachines, comprising two or more shakerbars, provided, upon their lower edges, with a plurality of offsets or teeth having inclined faces as deseribed,crossbars or slats in pairs, spaced from each other as described, arranged upon each inclined face, the lower bar of each pair extending below the spaces to form a stop for the straw, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD HUBER.
